First time making home-made yogurt...did I mess up?

I'm doing the specific carbohydrate diet which requires that I make my own yogurt since it needs to ferment for 24 hours. Now, before I realized that I wasn't supposed to, I did stir it during the process because I wanted to check the temperature (people were complaining that it got too high and I wanted to make sure it was okay). It finished last night and I stuck it in the fridge. This morning, it looked curdled. I used a whisk and it actually smoothed out okay, but it doesn't feel quite as smooth as I would expect. It smells and tastes mostly okay, it's very sour but not in a spoiled kind of way. I don't know what it's supposed to taste like since it's my first batch. The texture feels a little off but I can't tell if the problem was that I fail at reading directions and stirred it when I shouldn't have, or if it really did go bad. Is it okay? Is it safe? Or should I scrap this batch and start over?
